Description of the invention: [Technical field to which the invention belongs] The present invention relates to a device for inspecting a semiconductor element, which has a substrate holder on which a wafer or a microchip to be inspected is fixed. A semiconductor component of a wafer or a microcomputer component. The present invention further relates to a method for inspecting a semiconductor element, in which a substrate holder is provided, on which a semiconductor element to be inspected is fixed. The semiconductor element is observed by an observation device, and particularly by a microscope having at least one objective lens. [Prior Art] Optical devices are particularly suitable for inspecting the surface of a wafer. As is known from European Patent No. 4 5 5 8 5 7, by measuring the light reflected from the surface of the wafer, the inspection of the wafer can be achieved. In addition, the currently known optical devices use image recognition to detect various changing characteristics on the surface of a wafer or semiconductor substrate. In this context, the wafer is usually illuminated with a bright field of view or scanned with a camera φ, such as a matrix camera or a linear camera. In addition, U.S. Patent No. 6,5,87,193 is further known for surface inspection of a wafer. The wafer surface inspection selects an illuminance and scans the wafer in a linear form. The irradiation line is projected on the surface of the wafer, so a two-dimensional image can be generated. A method and an apparatus for inspecting a wafer are further disclosed in U.S. Patent No. 2003/0202178 A1. It is explained here that a ray is projected on the wafer, so that it strikes an edge of the wafer. With an image processing unit, 200535967 the edge of the wafer can thus be sensed and processed. Defects of the wafer can be detected by comparing the detected edge image with a stored comparison image. These systems for inspecting wafers are designed for incident light inspection. The main reason is that silicon wafers are opaque in the visible, ultraviolet, and deep ultraviolet wavelength regions. Silicon becomes transparent only at wavelengths above 1 000 nm. Within these wavelength ranges, it is possible to detect the characteristics below the surface of the wafer or the characteristics of the front side of the wafer through the back side. However, for transmitted light inspection of wafers, the known light illumination concept of transmitted light microscopy requires a transmitted light illumination optical system under the microscope and a transmitted light microscope carrier under this concept Objects, but not implemented in current inspection systems. The conventional inspection system expansion requires a completely new design to include transmitted light inspection features. In particular, these systems need to be equipped with a wafer microscope stage suitable for transmitted light. Compared to incident light wafer microscope stages used so far, it has an unobstructed through-hole for the entire wafer diameter Transmitted light illumination within range. Integrating a transmitted light irradiation system φ into the wafer inspection device is also a design option to consider. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to develop a known wafer / semiconductor inspection device so that it can be used in transmitted light applications. The main object according to the present invention is achieved by the device and method described in the first patent application scope. According to the present invention, a special substrate holder is provided for irradiating one of the wafers. Integrated into it. The semiconductor device may include, for example, a wafer, a microchip, or a microcomputer 200535967. So it goes without saying that a plurality of microchips or microcomputer component groups will be formed on one wafer. The term "wafer" is used as an abbreviation, but not as a self-limiting name. In order to inspect the semiconductor element or wafer with transmitted light, the irradiation device 'is provided so that it emits light of a wavelength in the infrared wavelength region. The wafer is transparent and brightens in the infrared wavelength region. If the geometric points are taken into consideration, the substrate holder can be set on a wafer stage 'provided as an additional device. The irradiation device emits an irradiation beam to illuminate the wafer. The wafer is therefore irradiated from below, that is, by the Φ end face far from the objective lens. This allows the transmitted light to be checked, eliminating the need for complex corrections to the overall equipment design. In principle, with the device and method of the present invention, the characteristics of the deep layer of the wafer and the surface under the wafer can also be inspected with transmitted light. This is quite helpful for quality control when making a chip package, because the functional surface of the chip is far from the cover. In a preferred embodiment, a diffusing device is provided to facilitate achieving high intensity and consistency under the irradiated radiation environment; for example, using a diffusing panel; in particular, diffusing paint on one of the edges of the substrate holder; It is a diffused-focusing optical system. These diffusion devices can be used one by one or with another device. In another embodiment, the irradiation device may include at least one light guide body integrated into the substrate holder. Light having an appropriate wavelength can thus be guided through the light guide to the substrate holder. Similarly, infrared light emitting diodes, especially a light emitting diode matrix, can be provided on the substrate holder. The light-emitting diodes can be directly disposed on the inside of the side wall of the substrate holder or integrated into the latter. A device is produced and the wafer is then irradiated. The wafer is scattered and irradiated, that is, before the wafer is contacted, the irradiation beam is transmitted to a diffusion device, such as a glass carrier, a diffusion plate, a diffusion coating, or a diffusion focusing optical system that carries the wafer. Therefore, if the irradiation device is appropriately selected, it can be conveyed along the inside of the substrate tray, and a large area of distributed configuration can be achieved. In particular, an incandescent light or a locally defined light-emitting diode array can be used here, which is arranged in a certain unit, where the unit is removed at the same time as the scanning stage. With the integrated irradiation system, a wafer inspection device illuminating one of the wafers with a transmitted light is constructed. Therefore, there is no need to redesign the scanning stage, the basic structure, or the microscope unit. Conversely, units currently on the market can be improved with this transmitted light device. The following illustrations are advantages and advantageous embodiments of the invention and are described with respect to these drawings. [Embodiment] FIG. 1 is a diagram illustrating a characteristic configuration of a wafer inspection apparatus 10 according to the present invention. A scanning stage 14 constitutes the microscope stage, and the scanning stage 14 is integrated on a basic structure 12. The wafer 18 to be inspected is set on or in the scanning stage 14, and the inspection is performed directly or on a substrate holder 16 on the scanning stage. The preferred inspection device is a microscope 20, which is connected to a basic structure 12 via a carrier unit 22, and can be used as a magnified inspection of the wafer 18. The microscope 20 includes: at least 200535-967 an objective lens 24, which represents an imaging optical system, and can be inspected using different magnifications. The magnified features can therefore be viewed directly via an eyepiece 26 or a suitable CCD camera 28. The signals of the camera 28 are transmitted to a screen 30 according to their purpose. An electronic device 32 is also provided, and the electronic device 32 can realize system automation. The electronic unit 32 is used to control the scanning stage 14 or the reading camera 28 in particular. The substrate holder 16 is usually configured to accommodate a wafer or a semiconductor element 18 to be inspected so that it can be fixed during the inspection. According to the present invention, p includes an irradiating device for transmitting light to irradiate the wafer 18. As shown in Fig. 2, the scanning stage 14 includes two axes 36 and 34, and the two are interchangeable on the X and Y axes. Each point 35 on the wafer 18 can be moved under the optical axis of the microscope objective lens 24 for inspection (Fig. 1). The wafer 18 is fixed on the substrate holder 16 and irradiated by an irradiation device integrated in the substrate holder 16. FIG. 3 illustrates the substrate holder 16 in the first embodiment. An irradiation device 38 is integrated in the substrate holder 16. The irradiation device 38 includes at least one light guide 39. The substrate carrier 16 is close to the bottom, that is, opposite to the wafer 18, and is opened at the top, that is, it is opened in the direction of the wafer 18. During the inspection, the wafer 18 must be set on a glass plate 46. Furthermore, according to the requirements of the flatness of the crystal circle 18 and the consistency of the irradiated light, the wafer can be directly placed on the substrate holder 16 even if a glass plate is not provided. So far, based on this factor, the side edges of the wafer 18 are provided on the support edges 44 on both end faces of the substrate holder 16. The small holes that can be applied to the wafer 18 through a vacuum device 18 must be provided to the glass plate 46, so that the wafer 18 can be fixed. 200535967 In terms of illumination, the light system is guided through the at least one light guide body 39 to the inside of the substrate holder 16. The side walls extending around the periphery of the substrate holder 16 are selected as a number of preferred entrances. The light guides 39 are all oriented from the top to the bottom at an inclined angle, but they can also enter the substrate holder from the bottom to the top or enter horizontally. The infrared radiation has a wavelength of an irradiation radiation 48 which is derived from the infrared radiation of the light guide 39. The irradiation radiation 48 is reflected to the inner walls of the substrate holder 16 in a distributed manner, and thus is radiated from the bottom to the top through the wafer 18. If conditions permit, the light is radiated through the glass plate 46. In order to enhance the light intensity and consistency, the inner walls of the substrate holder 16 must be provided with a highly diffuse reflective reflection layer to form a diffusion device. A focusing optical system 37 at the exit surface of the light guide 39 may be provided as part of the irradiation device 38. With this system, these emission characteristics can be optimally adapted to the geometric internal configuration of the substrate holder 16. In addition, the focusing optical system 37 itself already has scattering characteristics, and these characteristics are especially realized by a rough surface. In order to achieve better uniformity of the irradiated radiation 48, the glass plate 46 must also have scattering characteristics. An embodiment of the wafer stage is further described in FIG. 4. In this figure, the light emitting diode 40 is a type of irradiation device. The irradiated light is preferably completely generated inside the substrate holder 16, and the light-emitting diodes 40 are arranged on the base layer of the support holder 16 in a planar arrangement. An embodiment of a light emitting diode formed by a planar light emitting diode array is particularly applicable here. In order to improve the illumination uniformity of the 18 plane of the wafer, a diffusion plate 50 may be disposed between the light emitting diode 40 and the wafer 18. At this point, the glass plate 46 also resumes its diffusion characteristics. -10- 200535967 Because the light emitting diode 40 generates unexpected heat during operation, it is assisted by a control device, such as the electronic unit 32, which will enable better functions to be further realized. So far, the control device controls the light emitting diode 40, and only the special diodes currently set under the checkpoint 3 5 (Figure 2) emit light. As a result, even if the irradiation is uniform and appropriate, the heat is greatly reduced. Therefore, only a part of the light emitting diode is used to irradiate the wafer 18. The operations listed for the consistency of the irradiation radiation 48 are all examples. In general, all known methods to produce a uniform background illumination can be used, especially those methods applied to LCD flat screens. The glass plate 46 is not necessarily made of glass. On the contrary, in each embodiment, any transparent material that can see the irradiation lines 48 can be used. An embodiment of the substrate holder 16 is further described in Fig. 5 '. The light source of the irradiation device used in this embodiment is a locally defined light source, such as a conventional incandescent lamp 42 or a locally defined light-emitting diode array. The incandescent lamp 42 is fixed below the sub-point 35 to be inspected so that the latter is completely irradiated. Therefore, the incandescent lamp is guided to the inspection point 35 via one of the X-Y positioning units 52 in the substrate holder 16 and is preferably synchronized with the scanning stage. In particular, a unit containing the actual light source and a focusing optical system having selective diffusion characteristics with irradiation uniformity can be used as the irradiation source. The illuminating device and a focusing optical system thus include a locally defined light emitting diode array. In a further preferred embodiment of a substrate holder 16, the locally defined illumination source (incandescent lamp) 42 with respect to the microscope 20 is also set in a fixed manner. This is illustrated in Figure 6. The substrate holder 16 provided here is not a -11-200535-967 as a completely closed cylinder, but a U-shaped element in a cross section. Also in all the embodiments described so far, the substrate holder 16 is moved with the scanning stage 14 (FIG. 1) during the positioning period. The light source (incandescent lamp) 42 is disposed on the supporting arm 54 and is fixed between the brackets of the U-shaped substrate bracket 16, that is, the upper and lower end surfaces. This ensures that the bearing arm 54 and the generated light source (incandescent lamp) 42 can be positioned according to requirements without causing collision. One advantage of this embodiment is that it eliminates an X-Y positioning unit, which can remove a large amount of heat and high energy consumption generated by a large area light emitting diode array. B Alternatively, the irradiating device 38 can be used as a light guide cable, and its guiding route is along the carrying arm 54 and it has a tilting and equalizing optical system fixed at the exit end, and the substrate holder can be 1 6 Dispersion of external light.
